CLEVIS FOR FLOWS.

Specification of Letters Patent.

Patented March 24, 1908.

To all whom it may concern:

Be it known that I, CHARLES C. RANKIN, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Clevis for Plows, of which the following is a specification.

My invention relates to improvements in means for securing the clevis to the beam of a plow; and the objects of my improvement are strength, facility of adjustment, and simplicity and chea ness of construction. These objects I attain y means of the device illustrated in the accompanying drawing in which l igure 1 is a perspective view of the clevis in position for use upona tubular plow beam of square cross section; I ig. 2 is a vertical longitudinal section of the clevis mounted upon the end of a tubular beam of square cross section which has been rounded at one end; Pig. 3 is a cross section of the clevis showing an adjustment at an angle of about 45 degrees with the standard; Fig. 4 is a perspective view of the clevis mounted upon a tubular plow beam of circular cross section.

Similar reference numerals refer to similar parts throughout the several views of the drawings.

The clevis 3 consists of the casting or stamping 2 slitted, flanged, and fastened by the bolts 4, as shown in Big. 3. As the beam 1 is made of round tubing or of square tubing rounded at the end, and the cylindrical wall of clevis 3 encircles the end of the beam, the clevis 3 may be rotated upon the end of the beam or removed when the bolt 4 is not tightened. At any desired angle the bolt 4 may be tightened, thus securely fastening the clevis in place. By this means the plow way not only be given pitch in the or dinary manner, by changing the draft hook from one to another of the holes provided in the clevis, but also the width of the furrow may be broadened or land given to the plow by shifting the angle of the clevis. This clevis may be made very light by using malleablle or steel castings or stampings of sheet stee It will be observed that no special skill is required to affix this clevis to the plow beam norto adjust it when in use.

Having thus described my invention so that any one may make and use it, I claim- 1. A plow-clevis, having a cylindrical portion to fit over the draft end of a plow-beam, the wall of said cylindrical portion being slit longitudinally and having longitudinal flanges provided with holes for bolts for clamping said cylindrical portion on said beam.

2. A plow-clevis, comprising a transverse flat portion provided with a row of transverse holes, a socket member to fit over the end of a plow-beam adapting the clevis to be r0- tated on the plow-beam, said socket member being longitudinally slit and provided with means for clamping over the end of the plowbeam.
